A generalized geometric mechanics theory for multi-curve-fold origami: vertex constrained universal configurations
Zhixuan Wen, Pengyu Lv, Fan Feng +1
Folding paper along curves leads to spatial structures that have curved surfaces meeting at spatial creases, defined as curve-fold origami. In this work, we provide an Eulerian fra…
An effective slip boundary for micro-structured surfaces containing a second immiscible fluid
Yufan Cao, Yixin Zhang, Pengyu Lv +1
Effective slip boundary conditions for flows over periodic micro-structured surfaces containing a secondary immiscible fluid are derived. The primary fluid is in the Cassie state,…
Physiochemical hydrodynamics of the phase segregation in an evaporating binary microdroplet
Yaxing Li, Pengyu Lv, Christian Diddens +1
Phase segregation triggered by selective evaporation can emerge in multicomponent systems, leading to complex physiochemical hydrodynamics. Recently, Li et al. (Phys. Rev. Lett., v…
Self-Propelled Detachment upon Coalescence of Surface Bubbles
Pengyu Lv, Pablo Peñas, Hai Le The +4
The removal of microbubbles from substrates is crucial for the efficiency of many catalytic and electrochemical gas evolution reactions in liquids. The current work investigates th…
Origami spring-inspired shape morphing for flexible robotics
Qianying Chen, Fan Feng, Pengyu Lv +1
Flexible robotics are capable of achieving various functionalities by shape morphing, benefiting from their compliant bodies and reconfigurable structures. Here we construct and st…
Gravitational effect in evaporating binary microdroplets
Yaxing Li, Christian Diddens, Pengyu Lv +3
The flow in an evaporating glycerol-water binary sub-millimeter droplet with Bond number Bo 1 is studied both experimentally and numerically. First, we measure the flow field…
Liquid-liquid displacement in slippery liquid-infused membranes (SLIMs)
Hanieh Bazyar, Pengyu Lv, Jeffery A. Wood +3
Liquid-infused membranes inspired by slippery liquid-infused porous surfaces (SLIPS) have been recently introduced to membrane technology. The gating mechanism of these membranes i…
Evaporation-triggered segregation of sessile binary droplets
Yaxing Li, Pengyu Lv, Christian Diddens +4
Droplet evaporation of multicomponent droplets is essential for various physiochemical applications, e.g. in inkjet printing, spray cooling and microfabrication. In this work, we o…
Evaporating pure, binary and ternary droplets: thermal effects and axial symmetry breaking
Christian Diddens, Huanshu Tan, Pengyu Lv +4
The Greek aperitif Ouzo is not only famous for its specific anise-flavored taste, but also for its ability to turn from a transparent miscible liquid to a milky-white colored emuls…
Evaporation-triggered microdroplet nucleation and the four life phases of an evaporating Ouzo drop
Huanshu Tan, Christian Diddens, Pengyu Lv +3
Evaporating liquid droplets are omnipresent in nature and technology, such as in inkjet printing, coating, deposition of materials, medical diagnostics, agriculture, food industry,…
